Can I make this sandwich ahead?
Assemble just before serving to keep the baguette crispy and prevent sogginess from the tomato and pesto.
How do I crisp the prosciutto?
Pan-fry on medium-high heat for 2-3 minutes per side until edges curl and it's golden, or bake at 400°F for 8-10 minutes on a lined baking sheet.
Can I substitute fresh basil if I don't have it?
Yes — the pesto already contains basil. If making pesto from scratch, use fresh basil, pine nuts, garlic, Parmesan, and olive oil.
What's the best way to slice the tomato?
Use a serrated knife and slice 1/4 to 1/2 inch thick. Pat dry with paper towels to prevent excess moisture.
Can I use regular mozzarella instead of buffalo?
Yes, but buffalo mozzarella has a creamier texture and richer flavor. Fresh fior di latte is a good alternative.
